Every item in a store is discounted by 20%. Paige buys T-shirts that regularly cost $15 during the sale. She also pays 6.5% in tax, which is added after the discount is applied. Which calculations can be used to determine the total amount Paige paid for the T-shirt, including sales tax?

$12.78.

Step-by-step explanation:

The discount is 20% so:

Total payment  before tax = 15 - (15 *20/100) = $12.

Now we add the 6.5% tax:

Total payment after tax = 12 + (12 * 6.5/`100) =  $12.78.

Paige paid $11.22 for the T-shirt, including sales tax

Step-by-step explanation:

Paige buys T-shirts that regularly cost $15 during the sale. If a 20% discount is applied, the value of the discount would be

20/100 × 15 = 0.2 × 15 = $3

The price of the T-shirt would be

15 - 3 = $12

She also pays 6.5% in tax, which is added after the discount is applied. This means that the amount of tax that she paid is

6.5/100 × 12 = 0.065 × 12 = $0.78

Therefore, the total amount that Paige paid for the T-shirt, including sales tax is

12 - 0.78 = $11.22
